Adding a serial port

UART pads

There is a 3pin 2.54mm pitch header near the wifi module, called "UART_0" (P3 - Debug Port). All you have to do is attach some jumper wires according to our UART howto.

Variants

At some point in 2015, Linksprite started selling an updated variant of the pcDuino V3 called pcDuino v3B (or pcDuino3B). Compared to the original board, v3B updated the ethernet connection to Gigabit Ethernet. Other than that, the board layout stayed the same.
